I put a similar type of light by Denali on my HD Ultra, made a huge visibility difference especially during the day, after mounted I never again had anyone start to pull out on me from an intersection. Will have to look at these for the Ranger I just purchase.
To add to the conversation, one can purchase from Ford a brake controller ($339), looking at the components of that its plug and play, but I think that a less expensive and easier option would be to purchase a controller which is blue tooth compatible, but you do lose the built in safety...
